**Problem 9.5:**
**Objective:** Propose reagents for the following transformation.
**Reaction Description:**
The reaction involves the conversion of a cyclopentyl alkyne into a 1-cyclopentylethene. The starting material is a five-membered ring (cyclopentane) attached to a carbon-carbon triple bond (alkyne). The product is a five-membered ring attached to a carbon-carbon double bond (alkene).
**Diagram Explanation:**
- **Starting Compound:** The molecule on the left is a cyclopentyl alkyne with a five-membered ring and a triple bond extending from it.
- **Product Compound:** The molecule on the right is a cyclopentyl alkene with a five-membered ring and a double bond terminating in an ethene fragment.
To achieve this transformation, the alkyne must be partially reduced to a trans-alkene using appropriate reagents. Possible reagents include Lindlar's catalyst (for syn-addition) to achieve the desired transformation selectively.
**Considerations:**
- The choice of reagent is crucial to control the stereochemistry of the alkene product.
- Selective hydrogenation methods are important for retaining specific functionalities in the presence of the alkyne.
